Overview
Race cooling is used to manage heat stress and protect performance in hot conditions.
It works alongside fueling and hydration — not instead of them.
The goal is simple: start cooler, stay cooler, and recover faster.
Cooling becomes more important as environmental heat, race intensity, and duration increase.
This protocol focuses on practical race-day cooling, not long-term heat adaptation.

Protocol Guidance
This protocol provides practical cooling strategies for before, during, and after racing.
Cooling must be simple, planned, and executable under race conditions.
Detailed preparation of equipment and logistics connects closely to Race Readiness, while hydration and sodium strategy connect to Race Fueling. Race Execution then helps the athlete adapt when heat, wind, surface, or race pressure changes how the cooling plan can be used.
Where relevant, all cooling strategies should be tested in training before being used in racing.
- Test all strategies in training before using them in racing
- Cooling should be planned before race day, not improvised on the day
- Use methods that are practical for the race format, support available, and athlete experience
- Nothing new on race day
- Connect cooling cues to Race Execution when conditions change the cost of racing
Cooling Rules
- Start cool, not heat stressed
- Cooling works best when started early
- Do not rely on hydration alone to manage heat
- Avoid overheating during warm-up
- Use practical methods you can execute under pressure
- Cooling should not compromise fueling, handling, or race position
- The hotter the race, the more important the cooling plan becomes
Cooling Quick Start
Use this simple approach for hot race days.
- Stay in shade before the start
- Use cold drinks with sodium
- Warm up, then cool again before the start
- Separate drink bottles and cooling bottles
- Use feed zones and support for cooling where possible
- Cool immediately after the finish
Cooling Priorities
Cooling should follow a clear order of importance. The aim is not to do everything — it is to do the most effective practical things at the right time.
Cooling Priority Order
| Priority | Focus | Why it matters |
|---|---|---|
| 1 | Reduce heat before the start | Starting hot limits performance before the race is really underway. |
| 2 | Control warm-up heat | A poor warm-up in the heat adds unnecessary thermal strain. |
| 3 | Use practical in-race cooling opportunities | This helps slow heat accumulation during the race. |
| 4 | Cool immediately after the finish | Fast post-race cooling improves recovery and athlete safety. |
Decision Principle
- Use the highest-value cooling method available
- Prioritise the methods that fit the race and support structure
- Do not create more complexity than the athlete can execute
Pre-Race Cooling
Pre-race cooling is often the highest impact phase. Most heat issues begin before the race starts.
The athlete should aim to arrive on the line prepared and thermally controlled, not already carrying unnecessary heat load from the venue, the sun, or an overdone warm-up.
Goals
- Start race cool and comfortable
- Minimise unnecessary heat exposure before the start
- Protect the quality of the warm-up
- Create a larger thermal buffer before overheating becomes performance-limiting
Practical Pre-Race Steps
- Stay in shade as much as possible
- Limit standing in direct sun
- Use cold towels, ice, or cooling vest if available
- Use cold drinks with sodium
- Keep clothing minimal until needed
- Move efficiently through venue tasks so cooling opportunities are not wasted
- Know where shade, water, and support are before the race
Internal Cooling (Ice Slushies)
- Use ice slushie drinks before the start to reduce internal temperature
- Best used in the final 30–60 minutes before racing
- Small repeated intake is usually better than one large volume
- Combine with normal hydration and sodium intake
- Do not overconsume and create gut discomfort before the race
- Works best alongside external cooling such as shade, towels, or ice
- Particularly useful in hot, high-intensity, or long races
- Test this strategy in training before using it in racing
Pre-Cooling Clothing (Socks, Gloves, Kit)
- Use cooled socks or gloves before the start to reduce heat load
- Store them in a cool bag, cooler, or with ice before use
- Put them on shortly before the start to retain the cooling effect
- This can support peripheral and palmar cooling
- Avoid excessive wetness that affects comfort, feel, or control
- Do not start the race with cold-induced numbness
- Test comfort and practicality in training before racing
Short-Term Heat Preparation (Race Week)
- Prioritise freshness over adaptation when the race is close
- Avoid heat fatigue in the days before racing
- Stay cool, hydrated, and rested
- Avoid unnecessary exposure in peak heat
- Recon in extreme heat often adds fatigue without meaningful benefit
- Short timelines do not create adaptation — they create fatigue
- Arriving fresh is often more valuable than forcing heat exposure
In-Race Cooling
In-race cooling depends on race format, support, and safety. It must not compromise race performance.
Cooling during the race is useful when it is practical, safe, and planned in advance.
Cooling Methods
- Cold drink bottles
- Dousing bottles
- Ice socks or ice in jersey
- Cold bottles from team car or roadside support
- Use feed zones as cooling opportunities when available
Bottle System (Critical)
- Separate drink bottles and cooling bottles
- Plan bottle sequence before the race
- Know exactly what each bottle is for
- Do not compromise fueling by misusing bottles
- If using a dousing bottle, make sure the rider knows it is for cooling and not drinking
- Mark bottles or use a simple system if needed
Ice Socks (Real-World Application)
- Fill a sock, mesh, or simple cooling wrap with ice and secure it well
- Can be handed from roadside support or team car
- Often attached to a bottle for easier transfer to the rider
- Rider can place it in the jersey on the upper back, or hold it briefly before placing
- Best used during steady sections, not technical racing or high-risk handling moments
- Avoid overfilling, leaking, or poor positioning that causes discomfort
- Very effective in sustained hot races when support is available
- Test the handoff method, placement, and feel in training before racing
Dousing Strategy
- Use water bottles for external cooling
- Apply to head, neck, arms, and torso
- Use after feed zones or when safe
- Avoid using drink bottles if fluid availability is limited
- Dousing is most valuable in hot, exposed racing where evaporation can help
- Do not let cooling actions disrupt position, handling, or awareness
- Practice bottle handling and dousing timing in training where possible
When to Cool
- After feed zones
- Before long exposed sections
- When heat load is clearly building
- When a rider is beginning to feel thermally strained but can still act safely
- Only when safe and does not compromise race position
Post-Race Cooling
Cooling should begin immediately after finishing when heat stress is high.
In very hot races, cooling may be the first priority before full recovery routine begins.
Immediate Actions
- Move to shade immediately
- Remove excess clothing
- Start fluids with sodium
- Use cold towels, ice, or water
- Do not stand around in direct sun after finishing
If Overheated
- Prioritise cooling over routine
- Sit or lie in shade
- Use aggressive but safe cooling methods if needed
- Monitor for signs of heat stress such as dizziness, confusion, chills, or unusual distress
- Escalate support if symptoms are concerning
Recovery Integration
- Cooling comes before full recovery routine if the athlete is overheated
- Combine cooling with hydration
- Resume nutrition once cooling is underway
- The hotter the race, the more important immediate cooling becomes
Practical Cooling Tools
Cooling only works if the equipment and supplies are available, prepared, and easy to access.
This is where Race Cooling connects directly to Race Readiness.
Cooling Setup and Readiness
- Cooling strategies depend on preparation before race day
- Bring a cooler or chilly bin with ice, bottles, and cooling tools
- Prepare ice socks, cold towels, and frozen bottles in advance
- Ensure access to water for dousing if needed
- Plan how cooling will be delivered (self, roadside, or team car)
- Set up cooling equipment so it is easy to access under time pressure
- Cooling only works if it is available and ready when needed
Ice Vest
- Best used before race or after warm-up
- Use while stationary, not during hard efforts
- Remove before final race prep
- Combine with shade for maximum effect
- Particularly useful when there is a long wait between warm-up and the start
- Test fit, comfort, and timing in training before racing
Ice Socks
- Fill with ice and secure tightly
- Place on neck or upper back
- Can be delivered via roadside or team car
- Attach to bottle for easier handoff if useful
- Can be used before the start, in race, or after the finish
- A low-tech, high-value cooling method when support allows
- Test comfort, placement, and handoff method in training
Frozen / Slushy Bottles
- Use partially frozen bottles rather than solid ice blocks
- These can support both cooling and hydration
- Hold in the hands for added palmar cooling if useful
- Most effective early in the race or before the start
- Know which bottles are for drinking and which are primarily for cooling
- Test in training to understand melt rate, drinkability, and handling
Dousing Bottles
- Used for external cooling only
- Apply to head, neck, torso, and arms
- Keep separate from drink bottles
- Particularly useful in dry, hot, exposed conditions
- Less useful if bottle supply is limited and fluid needs are high
- Practice safe bottle handling in training where possible
Cold Towels
- Use before start and after finish
- Apply to neck, head, and torso
- One of the simplest and most effective pre- and post-race tools
- Works best when combined with shade and cold fluids
Shade and Fans
- Most effective basic cooling strategy
- Use proactively, not reactively
- Avoid standing in sun unnecessarily
- Fans are useful in staging, warm-up reset, and recovery areas
- Even when other tools are limited, shade should still be used deliberately
Palmar Cooling
Palmar cooling uses the hands as an additional cooling surface.
It is simple and effective, but should be used with control.
How to Use
- Hold cold bottles or cans in the hands
- Use cold packs wrapped so they are cool, not painfully freezing
- Use during waiting periods, after warm-up, or post-race
- Best used in combination with shade and broader cooling
When to Use
- Before the start while waiting in heat
- After warm-up to reduce heat load
- Immediately after the finish
Limits and Practical Notes
- Avoid excessive cooling that reduces hand feeling or dexterity before the start
- Do not go to the line with numb or unresponsive hands
- Ease off intense hand cooling in the final minutes before racing
- Palmar cooling is a support strategy, not the primary cooling method
- Test cooling level in training to avoid loss of hand function before racing
Warm-Up and Cooling
Warm-up must prepare performance without creating excessive heat load.
The hotter the day, the more carefully warm-up and cooling need to work together.
Key Principles
- Warm up enough, but not excessively
- Shorten warm-up in hot conditions when appropriate
- Cool after warm-up before the start
- Avoid standing in the sun after warming up
- Time trials require warm-up, while many road races may require less
Practical Notes
- If the race has a long neutral or staged delay, avoid carrying unnecessary heat out of the warm-up
- A strong warm-up followed by poor cooling can leave the athlete worse off than a simpler routine
- Cooling after warm-up is often as important as the warm-up itself in hot conditions
Putting It Together
Race cooling works best as a simple connected system.
Start cool → warm up without overheating → cool again before the start → use practical in-race cooling → cool immediately after the finish.
Cooling System Sequence
| Phase | Focus |
|---|---|
| Before | Reduce heat load |
| Warm-up | Prepare, then cool |
| During | Use practical cooling opportunities |
| After | Cool immediately |
Integration Notes
- Cooling should work with hydration and fueling, not against them
- Cooling setup depends on Race Readiness
- The best cooling plan is the one the athlete can actually use
- Race Execution applies the cooling plan when heat, pressure, bunch position, or feed access changes during the race
Common Mistakes
These are the most common cooling mistakes in hot racing.
- Starting the race already overheated
- Standing in sun too long before the start
- Overdoing warm-up in the heat
- No cooling plan
- Confusing drink and cooling bottles
- Using cooling methods that have not been tested in training
- Ignoring post-race cooling
- Trying to improvise cooling with poor equipment setup
- Overcooling hands or kit and reducing comfort or control
Review and Refine
Cooling strategies should be reviewed just like fueling and Race Execution.
The best cooling plans are built through practice and refinement, not guessed once.
- Did you start cool enough?
- Did warm-up create excess heat?
- Which cooling strategies worked best?
- What was practical and what was unrealistic?
- What will you improve next time?
